How to tune a car right: Part 3, tuning Mopar with OST Dyno

Not long ago, I wrote a story about a pony car tuned with a supercharger. The blower install had been done properly. Then the car's owner bolted on a set of great looking wheels wrapped in good looking but inexpensive rubber. On my first test drive, I couldn't get any of that supercharged sweetness to the ground. It was the perfect ride for parking in a Burger King parking lot on a Friday night. I tooled around on a Sunday drive, shaking my head that someone had spent five figures to get more power the right way, with a clean install, then wiped out the gains so thoroughly that the stock engine would likely have overwhelmed the tires. This got me thinking about the ways people ruin their quest for horsepower, either on the front end by not insisting on a clean install and paying the money for it, or on the back end with supplemental purchases like cheap tires or cheap gas. So I called three tuners, one focused on GM, one on Mopar, one on Ford, to find out what people should know about how to get the best power for their goals, and how to make sure they are able to use all that power. The first interview in this three-part series was with Blake Leonard at Top Speed Cincy in Cincinnati, Ohio, the second with Brandon Alsept at BA Motorsports in Milford, Ohio. This third and last interview is with Micah Doban at OST Dyno in Slippery Rock, Pennsylvania, a family business with more than 40 years of Mopar expertise specializing in Gen III Hemis, but tuning everything from land-speed cars and drag racers to Jeeps The interview has been edited for clarity and concision. Do people who come to OST generally know what they want? Probably 80% of the people who come in simply want more power with no particular ET goal [ET is a kind of bracket handicapped drag racing – ed.]. WhatÂ’s the best way to start a Mopar tune? The first thing is what people often skip, and that's to find a tuner or a shop. People will throw parts on their cars that the Internet said to, then go to a tuner who does things a different way, and [the tuner is] like ‘No we don't like to use these injectors, we don't like these parts.Â’ You have to find someone familiar with the parts that are on your car or that you're planning to put on your car. So having a goal and then finding a tuner who can help you with that goal is proper way to start. Exactly. And a lot of tuners have their own formula – and when I say tuner I mean someone that also does work to the cars.

2015 Dodge Charger Pursuit is ready to serve and protect

Okay speed freaks, it's time to update your cheat sheet of police headlights, as Dodge has just unveiled the new 2015 Charger sedan's police variant, the Pursuit.
Like previous Charger Pursuits, the 2015 model is based on a modified version of the civilian sedan, featuring the same basic batch of mechanicals and sheetmetal, while adding a number of items specific to the five-oh.
For 2015, cops can select from the same 3.6-ltier V6 and 5.7-liter Hemi V8 available to the civilian population, with former turning out 292 horsepower and 260 pound-feet of torque and the latter packing 370 ponies and 390 lb-ft. Even loaded down with equipment, Dodge claims the Hemi-powered cop car can hit 60 miles per hour in under six seconds, while both engines are expected return 26 miles per gallon on the highway (thanks to the V8's four-cylinder mode). Rear-wheel drive is standard with both engines, while V8 Pursuits can be fitted with all-wheel drive.

Junkyard Gem: 1991 Dodge Monaco LE

When Chrysler took over the American Motors Corporation in 1987, the hot-selling Jeep brand was the big prize of that deal. At a stroke, Iacocca's company got the XJ Cherokee (which remained in production into our current century) plus its Comanche pickup sibling, the Wrangler, the Grand Wagoneer, and the AMC Eagle as bonuses. The Eagle gave its name to Chrysler's new marque, which worked out well for quite a few years, and of course the PowerTech V8 engine began life as an AMC design. Yes, Chrysler made out like a bandit on the AMC purchase, but one of the most important acquisitions that came with that coup ended up being a Renault design from the last gasp of Kenosha: the Eagle Premier. Genetic material from this car made its way into Chrysler products for decades to come, and the Dodge Division got the opportunity to slap Monaco badges on the Premier for the 1990 through 1992 model years. Here's one of those super-rare cars in a Denver self-service yard. Dodge sold plenty of Detroit-designed Monacos from the 1965 through 1978 model years, and so the name seemed ripe for a revival in 1990. We rated the 1974 Dodge Monaco "Bluesmobile" #3 on the Best Movie Cars of All Time list, and Monacos may be found in countless cop movies and TV shows over the decades. Did the name belong on a Renault design? Absolutely! The radical-looking and big-selling Chrysler LH cars were built on a modified Eagle Premier chassis, enabling Chrysler to print money from a 1980s Renault design all the way through 2004. After that, Mercedes-Benz engineering (with a dash of Mitsubishi thrown in for good measure) got stirred into the mix, but I'm told by a Chrysler engineer that you can still see the Renault 25 structure beneath the dashboard in modern Challengers and Chargers. All of this comes thanks to Lee Iacocca's score of that advanced European car way back in 1987. One thing from the Premier that Chrysler dropped like a monkey dropping a red-hot penny once production of the Premier/Monaco ended: the PRV V6, a sophisticated-but-flaky overhead-cam V6 originally developed by a partnership between Peugeot, Renault, and Volvo (hence the acronym). This engine achieved its greatest fame as the powerplant that went into the DeLorean DMC-12. You could get the chugging AMC 2.5-liter straight-four in the Eagle Premier, but all the 1990-1992 Monacos got the 3.0-liter PRV, rated at 150 horsepower.
